Abstract: Wind power, because of its clean, efficient, renewable and other advantages, has become an important part of China's strategic action plan for energy development, and China has become the world's largest installed wind power capacity. With the arrival of the wind turbine retirement tide, the retired wind turbine blade (RWTB) has become a large solid waste material that China urgently needs to solve. Wind turbine blades are mainly prepared from glass fibre/carbon fibre/plant fibre reinforced composites, and the traditional treatment menthods are mainly landfill and incineration, which not only results in a large amount of wasted resources, but also leads to environmental pollution. The resourceful and high-value utilisation of decommissioned wind turbine blades has become a research hotspot of great concern to the country. This paper briefly describes the scale of installed wind power and the development scale of RWTB at home and abroad, overviews the existing recycling technologies (mechanical recycling, pyrolytic recycling, chemical recycling) of wind turbine blades, overviews the current status of recycling application of RWTB, summarises and analyses the strengths and weaknesses of various types of recycling technologies and the current status of their application. Analysed the prospect of RWTB recycling technology and application, put forward the "multi-method" gradient use and the "high efficiency and standardised full use" without secondary pollution are important research direction of RWTB recycling technology.
